bike computer questions

So I just bought a basic wireless bike computer (you know the one that counts the rotations of your tire) and tried it out on my route. I usually have morning route and an afternoon/evening route. The morning route is approx 60% on a MUP along a river (as in curved). I measured the distance using bikely.com and got 7.1 m, but the bike computer spit out 7.356?
Question: How accurate are the distance measurements on bike computers? Because a large part of my trip is on a MUP, exact measurements are not that easily made on bikely.com.
I'll try my afternoon route, which is more along streets to see if I get a more accurate reading.
thanks,
